BICYCLE-SEAT.

SPECIFICATION forming part of Letters Patent No. 274,163, dated March20, 1883. I Application filed September 21, 1882. (No model.) t

Seats, of which the following is a description sufficiently full,clear,and exact to enable any person skilled in the art or science to whichsaid invention appertains to make and use the same, reference being hadto the accompany-' ing drawing. forming a part of this specification, inwhich the figure is a sectional side elevation.

In ordinary bicycles the saddle of the seat is usually mounted on atlatspring which is rigidly attached. to the backbone of the machine. Thisspring, while taking up or neutralizing the vertical movements of theseat produced by passingovera rough road or track, does not take up orneutralize to any great we tent the horizontal'inoveinents produced bythe same cause.

Myinvention is designed to obviate this objection and to that end Iconstruct and arrange the parts which constitute the seat in anovel andunique manner, as hereinafter fully set forth and claimed, by which amore desirable and efi'ective device of this character is produced thanis now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant'withsuch matters from the following explanation, itsextreme simplicity rendering an elaborate description unnecessary.

In the drawing, A represents the main wheel, B the handles, 0 thesaddle, and Dthe backbone, of the bicycle. A semi elliptic spring, m, isrigidly secured to the backbone by the nuts and bolts d, each end ofthis spring carrying two pendulous links, a. a, which 7 are jointedtheretoin such a manner as to swingt'reelyin line with the springs.Aspring, E, is arranged horizontally'above the spring m, and has itsends as 00 curved down ardly and inwardly under the ends of the springm,where they are jointed to the lower ends of the links ca, as shown, thesaddle O being firmly secured to the upper side of the spring E by thenut and bolt 1 or in any other convenient manner.

In the use or my improvement it will be obvious that the jar or verticalmovements of the backbone I), produced by the wheel A in passing'over arough road or track, will be taken up or neutralized by the conjointaction of the springs E m, and also that the ill or disagreeable effectsof all horizontal movements of the seat produced by the wheel coming incontact with obstructions in its path will be overcome by means of thejointed pendulous links a a, and the peculiar manner of forming andconnecting the springs E m, whereby the spring E is enabled to move orswing slightly back and forth on the line of traverse followed by themachine.

Having thus explained my improvement, what I claim is-- l Thecombination of the bicycle-backbone D,

the upwardly-curved semi-elliptic spring tn,

the saddle U, attached to said longitudinal springs,substantially asdescribed.
